This research identifies vascular tissue-resident macrophages (VRMs) as essential protectors against abdominal aortic aneurysm (AAA) progression. These specific cells, located in the outer layer of the artery, secrete a protein called Sparcl1 to maintain vascular health. When Sparcl1 is absent, the growth factor FGF2 triggers abnormal lymphatic vessel growth and the formation of tertiary lymphoid ...去小宇宙查看完整单集简介

This review examines the neuroimmunometabolic co-evolution in cancer, detailing how the nervous system coordinates with immune and metabolic processes to influence tumor progression. At the tumor microenvironment (TME) scale, the authors explain how peripheral neurons—including sympathetic, parasympathetic, and sensory types—reprogram local metabolism and suppress anti-tumor immunity. Expanding to...去小宇宙查看完整单集简介

This article introduces GASTON, an unsupervised deep learning algorithm designed to analyze complex spatial transcriptomics data. By calculating a metric called isodepth, the tool creates a topographic map of tissue slices that functions similarly to elevation on a geographical map. This innovative approach allows researchers to identify spatial domains while simultaneously modeling both smooth ge...去小宇宙查看完整单集简介

This research article from Nature Neuroscience investigates the epigenetic landscape of the adult human central nervous system at a single-nucleus level. By analyzing chromatin accessibility and specific histone modifications, researchers identified a specialized epigenetic memory in oligodendroglia and astrocytes that mirrors early developmental stages. These unique signatures, particularly at HO...去小宇宙查看完整单集简介

The paper introduces scHiCAR, an innovative multiomics technology that simultaneously maps the transcriptome, epigenome, and 3D genome from individual cells. This method utilizes a plate-based combinatorial barcoding approach to achieve high throughput, allowing for the cost-effective analysis of millions of cells in a single experiment. Unlike previous techniques, scHiCAR excels at capturing long...去小宇宙查看完整单集简介

This paper describes the successful development and 180-day testing of a tissue-engineered esophagus in a growing large-animal model. Researchers created these functional grafts by microinjecting a decellularized porcine scaffold with the subject's own muscle-derived cells and fibroblasts, followed by maturation in a specialized bioreactor. This integrated approach, which utilized biodegradable st...去小宇宙查看完整单集简介

Researchers have developed spatial ATAC, a novel method designed to map chromatin accessibility within intact tissue sections. By integrating tagmentation with spatially barcoded oligonucleotides, the technique allows scientists to visualize the epigenomic landscape without losing critical anatomical context. Studies on mouse embryos demonstrated that this approach effectively identifies regulator...去小宇宙查看完整单集简介

Researchers have developed a myoneural actuator (MNA) designed to improve the performance of implantable biohybrid systems. By replacing a muscle’s native motor nerve with a sensory nerve, the scientists successfully redirected control from the central nervous system to a computer-controlled interface. This surgical innovation creates a more uniform axonal distribution, which enhances fatigue resi...去小宇宙查看完整单集简介

This study utilizes advanced cellular electron cryo tomography to map the physical transformation of Bacillus subtilis bacteria during infection by the bacteriophage SPP1. Researchers discovered that the virus establishes a distinct DNA replication compartment that excludes host ribosomes, despite lacking a traditional membrane or shell. A critical finding is that viral assembly begins at the inne...去小宇宙查看完整单集简介

The paper introduces the Extreme Environment Microbiome Catalog (EEMC), a massive genomic database documenting the microbial life found in Earth's harshest habitats. By analyzing thousands of metagenomes and isolates, researchers identified over 78,000 genomes and nearly 4 billion genes, many of which represent previously unknown species and lineages. This vast resource highlights the biosynthetic...去小宇宙查看完整单集简介
